METHOD OF MANUFACTURING SHOES.

@@SOO.

To all whom it may concern:

lle it known that l, VALRE LANDRY, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful lin roveinents in Methods of Manufacturing i hoes,I and l do hereby declare the :tollowinflr to be a full, clear, and exact description ot the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

lli/ly invention comprises a novel and practical method of manufacturing shoes, and has among othei` objects that of producing an improved article of toot-wear which is particularly flexible, durable and well adapted for intants, childrens and misses use; it contemplates also a method orre opera- "lon whereby, in comparison with other methods ot manutacturing shoes, the cost of production is materially decreased, time, la-

bor and materials econoinized, all unnecessary temporary process steps avoided, and the necessity oit employing special sewing machines obviated.

"With the aforesaid and other objects and advantages in view therefore, the present invention and successive method steps will be hereinafter particularly pointed out and set forth in the claims following. ln the accom anying drawings which form part of this application for l]etteiosV `Patent, and whereon like numerals reiter to corresponding parts in the several views: Figure l is an inverted perspective View oi"I a shoe in its first stages of manufacture under my improved method; Figs. 2 and 3 are fragmentary sectional views taken on' the lines 2-2 and 3 3 respectively, of Fig. l; Fig. 4 is a. transverse sectional view through the toe of a shoe in its second important stage of manufacture. after lasting but before the addition of an outer sole;

Fig. 5 is a view similar to Fig. 4 with` an outer sole added, thus illustrating the third important method step; and Fig. 6 is aperspective view of the finished product after the finishing operations have been performed.

Reference being had to the drawings and numerals thereon, 7 indicates a shoe-upper which may, of course, vary indefinitely in size, shape, material and style of manufacture; the numeral 8 indicates a lining for the upper aforesaid, by preference consist- Bpeoication of Letters atent.

Application ied November 23, 1910.` Serial No. 593,874.

in of light-weight canvas, drilling, soft pliable leather or like materials, 9 indicates a iexible insole preferably of soft leather and of approved outline; l is a relatively,-l stid--counter such as ordinarily employed at'v the heel of shoes between the up er 7 and its lining 8; il is the Welt, Whic as best shown by l? l, completely surrounds all oi2 the members 7, 8,' 9, l0 and 11 aforesaid; While the numeral l2 indicates a channelless outer sole as shown by Figs. and t3.

ln practicing my improved method an operator assembles one upper 7, its lining 8, insole 9, Welt l1 and heel counter lO-When the latter is employed-in the relative positions indicated by Fig. 3 of the drawings, holding these parts in this position they are neat passed continuously under the needle, which in eii'ect thus travels' completely around the shoe structure joining the several parts aforesaid by a continuous line ot stitches 13, as fully shown by Fig. l, and in fragmentary sections by Figs and 3 o the drawings. in accomplishing this method step, or the welting operation, it Will be observed that an ordinary straight needle may be employed, and that the resulting seam is an outside seam, this step being performed with the shoe in an unturned condition; aiid moreover, it will be noted, that because oi" such outside seam arrangement the iiecessit of an inside tillei` such as ordinarily emp oyed between the edges of an inturned welt is obviated, thus materially contributing to the ease and general flexibility ot the shoe.

At this stage the partially constructed shoe is lasted by the insert-ion of a suitable last 14as clearly illustrated by Fig. 4 of the drawings, the seam hereinbetore mentioned is practically liattened upon last 14, and the outer-sole 12 thereupon secured to the outer surface of the insole 9, preferably by cement just prior to the sole stitching operation, as clearly represented by Fig. 5 of the drawings. By the present method it will be particularly noted that the outer sole is channelless, a fact which materially contributes to the flexibility and comfort of the completed shoe in that a relatively thin piece of sole leather may be employed Without sacrificing strength and durability as compared with soles which have been Weakened by a channel cut, and stii'ened by a turned welt partially embedded therein.

this pcsitibn"`(see Fig. 5 sole 12 is firmly secured to `the out-turne welt .11 by a line vofstitclies 15, such asv ordinarily employed in sole stitchin operations, except that the resent meth f contemplates and rovides or extending saidstitches continuously l around the entire shoe structure from startingpoint to starting oint.

he foregoing met od steps having been performed substantiall mainsA only to finish t e shoe by the ordinary and well known operations of edge l trimming, setting, and finally polishing.

vAnd it` will Vbe particularly noted that b the method herelnbefore set forth the wet 11, upper v'if and linin 8 are connected together in l an unfoldeg condition by' a line f of stitches `extending continuously around the shoe and Passin transversely through the elements a oresai as indicated by Figs. 2 and 3 of the drawings. AThis accomplished the welt 11, as will be noted, is turned out-v 36; members havingthe usual overlapping fold in their lower edges'. A

' Havin thus set forth the leading and characterlstic features of my invention, its purposes and' objects, it should be understood' that. I do not confine myself-to the precise order and number of process steps described, butas-set forth it re-l What I do claim and desire to secure by Letters Patent is:

1. The method of making a shoe which consists in first unitin the welt the upper and the insole at the1r extreme marginal edges thel welt being secured entirel around the edge of the shoe, thereafter fo ding the welt outward into a plane coincident with that of the insole, and finally uniting an outer sole to the Welt.A

2. The method of making a shoe which consists in irst uniting the weltthe upper and the insole at theirl extreme marginal edges entirely around the vshoe in anunlasted condition, thereafter folding the welt outward into a plane coincident with that of the insole, and nally uniting an outer sole to the welt.

3; YThe method of making a shoe which consists in first uniting the welt the upper and the insole at their extreme 'marginal edges entirely around the shoe .in an unlasted condition, thereafter folding `the welt outward into' ab plane coincident withthat of the insole,'lasting` the shoe, and finally uniting an outer sole to the welt.

4. The method of .making a shoewliicli` consists in first uniting the welt the upper and a soft exible insolev at their extreme marginal edges entirely around the shoe, thereafter folding the Welt loutward into a plane coincident with that of the insole, and finally uniting an outer sole to the welt.

In testimony whereof I affix my signature, in presence of Atwo subscriblng witnesses. y y
